Notes

* An NTSC-U build dated nearly two months before the final.
* Starts with an intro video which is different to the one used in the final.
* Loading screens are slightly unfinished and do not include a loading bar.
* Has "Alpha" on the upper-left corner of the title screen.
* The logo on the title screen looks a bit different.
* The campaign type and level are not captioned on the main menu, and each use different icons.
* Has no music.
* The icons on the options menu are unfinished and look quite primitive.
* All missions appear to be enabled by default and selectable from the beginning, with the exception that the final level asks you to enter a code into the passgrid. The effects of using the grid appear to cause visual glitches.
* A number of text strings are different - e.g. "SELECT A LEVEL" rather than "SELECT MISSION".
* The in-game HUD is quite different.
* Has a crash handler screen which can be seen by loading certain levels.
* Contains a .MAP file.
